Cars enter a car wash at a mean rate of 2 cars per half an hour. what is the probability that, in any hour, exactly 5 cars will enter the car wash? round your answer to four decimal places.

  0.1563

Step-by-step explanation:

The Poisson distribution probability formula is given by :-

, where is the mean of the distribution and x is the number of success

Given : Cars enter a car wash at a mean rate of 2 cars per half an hour.

In an hour, the number of cars enters in car wash =

Now, the probability that, in any hour, exactly 5 cars will enter the car wash is given by :-

Therefore, the required probability = 0.1563
